Hard Drives - Internal

SORT BY:
Boost your computer's storage space by adding internal hard drives. Whether you're replacing a failing drive, adding an extra storage drive or building a new computer, these internal hard drives fit inside your tower case and connect to your motherboard via a SATA cable. This makes installation quick and simple.

Extended Storage
Discover internal hard drives with capacities from 160 GB to over 3 TB, allowing you to select the one that best suits your needs. Choose a small SSD drive as a backup drive on your computer to ensure you never lose vital information, or select large-capacity models for storing and organizing extensive media libraries of videos, photos and documents.

Fast Transfer Speeds
Enjoy lightning-fast transfer speeds with internal hard drives that feature rotational speeds of up to 10,000 RPM and cache sizes of up to 16 MB. The SATA interface on some drives offer data transfer rates of 6 Gb/s, making them fast and efficient when you need to move files between your computer and external hard drives or other devices.

Designed to Fit
Choose internal hard drives with a 2.5- or 3.5-inch size, depending on the needs of your computer. The 3.5-inch size often works best with older equipment, allowing you to upgrade rather than replace older computer models that still work well, and the 2.5-inch size fits inside most laptops, making them simple to install.

Easy Compatibility
Upgrade your Windows-based laptop or desktop with internal hard drives designed for use specifically with PCs. Some hard drives can be used with both Mac and PC machines, though they sometimes require a format change before installation in an Apple computer.
